Wow, this thread is kind of all over the place! :rotfl:
"Best jazz album ever", I agree, is a little like saying, "Best Rock Band ever".
For me, there's a couple:
The Quintet - Live at Massey Hall
Sonny Side Up - Sonny Rollins, Sonny Stitt, Dizzy Gillespie
Dahabenzapple - Joe Maneri
"Kind of Blue"
always makes me list for "desert island" picks, but it's already been mentioned, so I won't.
